Most decay modes (other than the semileptonic modes) that involve a neu-
tral K meson are now given as K0S
modes, not as K0 modes. Nearly always
it is a K0S
that is measured, and interference between Cabibbo-allowed
and doubly Cabibbo-suppressed modes can invalidate the assumption that
2 Γ(K0S
) = Γ(K0).

Most decay modes (other than the semileptonic modes) that involve a neu-
tral K meson are now given as K0S
modes, not as K0 modes. Nearly always
it is a K0S
that is measured, and interference between Cabibbo-allowed
and doubly Cabibbo-suppressed modes can invalidate the assumption that
2 Γ(K0S
) = Γ(K0).

B-particle organizationB-particle organizationB-particle organizationB-particle organization
Many measurements of B decays involve admixtures of B
hadrons. Previously we arbitrarily included such admixtures
in the B± section, but because of their importance we have
created two new sections: “B±/B0 Admixture” for Υ(4S)
results and “B±/B0/B0s /b-baryon Admixture” for results
at higher energies. Most inclusive decay branching fractions
and χb at high energy are found in the Admixture sections.
B0-B0 mixing data are found in the B0 section, while B0s -
B0s mixing data and B-B mixing data for a B0/B0
s admixture
are found in the B0s section. CP-violation data are found in
the B±, B0, and B± B0 Admixture sections. b-baryons are
found near the end of the Baryon section.
The organization of the B sections is now as follows, where
bullets indicate particle sections and brackets indicate re-
views.

B− modes are charge conjugates of the modes below. Modes which do not
identify the charge state of the B are listed in the B±/B0 ADMIXTURE
section.
The branching fractions listed below assume 50% B0B0 and 50% B+ B−production at the Υ(4S). We have attempted to bring older measurementsup to date by rescaling their assumed Υ(4S) production ratio to 50:50
and their assumed D, Ds , D∗, and ψ branching ratios to current valueswhenever this would affect our averages and best limits significantly.
Indentation is used to indicate a subchannel of a previous reaction. Allresonant subchannels have been corrected for resonance branching frac-
tions to the final state so the sum of the subchannel branching fractions
can exceed that of the final state.
For inclusive branching fractions, e.g., B → D± anything, the values
usually are multiplicities, not branching fractions. They can be greaterthan one.

B0 modes are charge conjugates of the modes below. Reactions indicatethe weak decay vertex and do not include mixing. Modes which do not
identify the charge state of the B are listed in the B±/B0 ADMIXTURE
section.
The branching fractions listed below assume 50% B0B0 and 50% B+ B−production at the Υ(4S). We have attempted to bring older measurements
up to date by rescaling their assumed Υ(4S) production ratio to 50:50
and their assumed D, Ds , D∗, and ψ branching ratios to current values
whenever this would affect our averages and best limits significantly.
Indentation is used to indicate a subchannel of a previous reaction. All
resonant subchannels have been corrected for resonance branching frac-tions to the final state so the sum of the subchannel branching fractions
can exceed that of the final state.
For inclusive branching fractions, e.g., B → D± anything, the values
usually are multiplicities, not branching fractions. They can be greaterthan one.

The branching fraction measurements are for an admixture of B mesons atthe Υ(4S). The values quoted assume that B(Υ(4S) → B B) = 100%.
For inclusive branching fractions, e.g., B → D± anything, the treatment
of multiple D’s in the final state must be defined. One possibility would
be to count the number of events with one-or-more D’s and divide bythe total number of B’s. Another possibility would be to count the to-
tal number of D’s and divide by the total number of B’s, which is thedefinition of average multiplicity. The two definitions are identical if only
one D is allowed in the final state. Even though the “one-or-more” def-
inition seems sensible, for practical reasons inclusive branching fractionsare almost always measured using the multiplicity definition. For heavy
final state particles, authors call their results inclusive branching fractions
while for light particles some authors call their results multiplicities. In theB sections, we list all results as inclusive branching fractions, adopting a
multiplicity definition. This means that inclusive branching fractions canexceed 100% and that inclusive partial widths can exceed total widths,
just as inclusive cross sections can exceed total cross section.
B modes are charge conjugates of the modes below. Reactions indicate
the weak decay vertex and do not include mixing.

The branching fraction measurements are for an admixture of B mesons
and baryons at energies above the Υ(4S). Only the highest energy results
(LHC, LEP, Tevatron, SppS) are used in the branching fraction averages.In the following, we assume that the production fractions are the same at
the LHC, LEP, and at the Tevatron.
For inclusive branching fractions, e.g., B → D± anything, the values
usually are multiplicities, not branching fractions. They can be greaterthan one.
The modes below are listed for a b initial state. b modes are their charge
conjugates. Reactions indicate the weak decay vertex and do not include
mixing.

Listings. The production fractions in b-hadronic Z decay or pp collisionsat the Tevatron are also listed at the end of the section. Values assume
B(b → B+) = B(b → B0)
B(b → B+) + B(b → B0) +B(b → B0s) + B(b → b -baryon) = 100%.
The correlation coefficients between production fractions are also re-
ported:cor(B0
s, b-baryon) = −0.240
cor(B0s, B±=B0) = −0.161
cor(b-baryon, B±=B0) = −0.920.
The notation for production fractions varies in the literature (fd , dB0 ,
f (b → B0), Br(b → B0)). We use our own branching fraction notation
here, B(b → B0).
Note these production fractions are b-hadronization fractions, not the con-
ventional branching fractions of b-quark to a B-hadron, which may haveconsiderable dependence on the initial and final state kinematic and pro-
duction environment.

In addition to the dominant decay mode to D D, ψ(3770) was foundto decay into the final states containing the J/ψ (BAI 05, ADAM 06).
ADAMS 06 and HUANG 06A searched for various decay modes with light
hadrons and found a statistically significant signal for the decay to φη only(ADAMS 06).

NOTES
[a] See the “Note on π± → ℓ±ν γ and K± → ℓ± ν γ Form Factors” inthe π± Particle Listings for definitions and details.
[b] Measurements of Γ(e+νe)/Γ(µ+νµ) always include decays with γ’s,
and measurements of Γ(e+νe γ) and Γ(µ+ νµ γ) never include low-energy γ’s. Therefore, since no clean separation is possible, we considerthe modes with γ’s to be subreactions of the modes without them, andlet [Γ(e+νe) + Γ(µ+ νµ)]/Γtotal = 100%.
[c] See the π± Particle Listings for the energy limits used in this measure-ment; low-energy γ’s are not included.
[d] Derived from an analysis of neutrino-oscillation experiments.
[e] Astrophysical and cosmological arguments give limits of order 10−13;see the π0 Particle Listings.
[f ] C parity forbids this to occur as a single-photon process.
[g ] See the “Note on scalar mesons” in the f0(500) Particle Listings . Theinterpretation of this entry as a particle is controversial.
[h] See the “Note on ρ(770)” in the ρ(770) Particle Listings .
[i ] The ωρ interference is then due to ωρ mixing only, and is expected tobe small. If e µ universality holds, Γ(ρ0 → µ+µ−) = Γ(ρ0 → e+ e−)× 0.99785.

[ii ] Re(ǫ′/ǫ) = ǫ′/ǫ to a very good approximation provided the phasessatisfy CPT invariance.
[jj ] This mode includes gammas from inner bremsstrahlung but not thedirect emission mode K0
L → π+π−γ(DE).
[kk] See the K0L Particle Listings for the energy limits used in this measure-
ment.
[ll ] Allowed by higher-order electroweak interactions.
[nn] Violates CP in leading order. Test of direct CP violation since theindirect CP-violating and CP-conserving contributions are expected tobe suppressed.

[rr ] This result applies to Z0 → c c decays only. Here ℓ+ is an average(not a sum) of e+ and µ+ decays.
[ss] See the Particle Listings for the (complicated) definition of this quan-tity.
[tt] The branching fraction for this mode may differ from the sum of thesubmodes that contribute to it, due to interference effects. See therelevant papers in the Particle Listings.
[uu] These subfractions of the K− 2π+ mode are uncertain: see the ParticleListings.
[vv ] Submodes of the D+ → K− 2π+π0 and K0S 2π+π− modes were
studied by ANJOS 92C and COFFMAN 92B, but with at most 142events for the first mode and 229 for the second – not enough forprecise results. With nothing new for 18 years, we refer to our 2008edition, Physics Letters B667B667B667B667 1 (2008), for those results.
[xx ] The unseen decay modes of the resonances are included.
[yy ] This is not a test for the ∆C=1 weak neutral current, but leads to theπ+ ℓ+ ℓ− final state.
[zz] This mode is not a useful test for a ∆C=1 weak neutral current becauseboth quarks must change flavor in this decay.
[aaa] In the 2010 Review, the values for these quantities were given using ameasure of the asymmetry that was inconsistent with the usual defini-tion.

[bbb] This value is obtained by subtracting the branching fractions for 2-, 4-and 6-prongs from unity.
[ccc] This is the sum of our K−2π+π−, K−2π+π−π0,K02π+2π−, K+ 2K−π+, 2π+2π−, 2π+2π−π0, K+K−π+π−, andK+K−π+π−π0, branching fractions.
[ddd] This is the sum of our K− 3π+2π− and 3π+3π− branching fractions.
[eee] The branching fractions for the K− e+ νe , K∗(892)− e+ νe , π− e+ νe ,and ρ− e+ νe modes add up to 6.19 ± 0.17 %.
[fff ] This is a doubly Cabibbo-suppressed mode.
[ggg ] The two experiments measuring this fraction are in serious disagree-ment. See the Particle Listings.
[hhh] Submodes of the D0 → K0S π+π−π0 mode with a K∗ and/or ρ were
studied by COFFMAN 92B, but with only 140 events. With nothingnew for 18 years, we refer to our 2008 edition, Physics Letters B667B667B667B667 1(2008), for those results.
[iii ] This branching fraction includes all the decay modes of the resonancein the final state.
[jjj ] This limit is for either D0 or D0 to pe−.
[kkk] This limit is for either D0 or D0 to p e+.
[lll ] This is the purely e+ semileptonic branching fraction: the e+ fractionfrom τ+ decays has been subtracted off. The sum of our (non-τ) e+
exclusive fractions — an e+ νe with an η, η′, φ, K0, K∗0, or f0(980) —is 7.0 ± 0.4 %
[nnn] This fraction includes η from η′ decays.
[ooo] Two times (to include µ decays) the η′ e+ νe branching fraction, plusthe η′π+, η′ρ+, and η′K+ fractions, is (18.6 ± 2.3)%, which con-siderably exceeds the inclusive η′ fraction of (11.7 ± 1.8)%. Our bestguess is that the η′ρ+ fraction, (12.5 ± 2.2)%, is too large.
[ppp] This branching fraction includes all the decay modes of the final-stateresonance.
[qqq] A test for uu or dd content in the D+s
. Neither Cabibbo-favored norCabibbo-suppressed decays can contribute, and ω − φ mixing is anunlikely explanation for any fraction above about 2 × 10−4.
[rrr ] We decouple the D+s
→ φπ+ branching fraction obtained from massprojections (and used to get some of the other branching fractions)
from the D+s→ φπ+, φ → K+K− branching fraction obtained from
the Dalitz-plot analysis of D+s
→ K+K−π+. That is, the ratio of
these two branching fractions is not exactly the φ → K+K− branchingfraction 0.491.
